Codebase Onboarding

For when you're dropped into an unfamiliar codebase and need to get oriented fast. It walks through the repository structure, identifies key architectural patterns, and maps out dependencies so you understand what connects to what. The approach is systematic: start with the project layout, move through the tech stack, then dig into how components interact. Honestly most useful in those first few days on a new team when you're trying to figure out where anything lives. Works best on codebases with some existing structure rather than complete chaos, though it'll give you a baseline either way.
